Roofing membrane industry: Thuringian Slate for your roof.
Thuringian slate has been considered a proven natural stone material for fireproof roofing and wall coverings for centuries. The mining and processing of slate in the Thuringian Slate Mountains, mainly in the region around Lehesten/County of Saalfeld, has a tradition that goes back to the Middle Ages.
In our Schmiedebach open pit slate mine, also known as "Oertelsbruch", Debus Schiefer GmbH produces slate products for the roofing and bitumen membrane industry from the clay slate deposit. The Schmiedebach slate mined there impresses with its dark blue color and its extraordinary flatness.
